ShellFile Error: missing assembly reference?

Question

I cannot find the namespace for ShellFile.

I have added using System.Windows.Shell and also tried loading the Windows7APICodePack through the package manager console:

PM> install-Package Windows7APICodePack

Installing 'Windows7APICodePack 1.0.0.0'.

Successfully added 'Windows7APICodePack 1.0.0.0' to CADBuilderGUI.

I just tried installing the later version 1.1.0.0 with:

PM> Install-Package Windows7APICodePack-Shell

but still no luck.

I am simply trying to get a thumbnail image of a file with:

ShellFile shellFile = ShellFile.FromFilePath(files[0]);
Bitmap shellThumb = shellFile.Thumbnail.ExtraLargeBitmap;

But it doesn't know what ShellFile is.

Any suggestions?

This is not a duplicate of this because PresentationFramework.dll is added by reference and I am building in Framework 4.0.

Wherefore

aside from adding using System.Windows.Shell; did you actually right click on the references node and add the reference manually as well..? – Snappish

yes, PresentationFramework.dll is an added reference – Wherefore

what ver of .net are you using 4.0 or 4.5 try to change from 4.5 to 4.0 then back to 4.5 and rebuild to see if the assembly gets picked in the .config file – Snappish

Yea I tried that too before I asked, and still didn't change anything – Wherefore

what platform are you targetting? – Construct

Readers - This worked for me perfectly. Installed NUGET packages WindowsAPICodePack-Core and WindowsAPICodePack-Shell. Added project reference to System.Drawing. Added additional line of code: shellThumb.Save(path, format). The output image was 256x256 16kb. – Kishke

Answer 1

PM> Install-Package WindowsAPICodePack-Core

PM> Install-Package WindowsAPICodePack-Shell

Install these two and it will work.

Answer 2

It turns out that after downloading the latest packages as stated from above, you have to browse to the .dll package locations and add both by reference, then add the package namespaces:

using Microsoft.WindowsAPICodePack.Shell;
using Microsoft.WindowsAPICodePack;

Wherefore

makes me wonder why adding this one would not do the trick using Microsoft.WindowsAPICodePack.Shell; in regards to dot dereference – Snappish
